Solution - Follow up 1  

White almost fills the black eye with a killing shape, the bulky five after playing at a. (In practice, White usually doesn't need to play a, but can count black's stones as being dead as they stand.)

Solution - Follow up 2  

If Black throws in at B2, White can still almost fill the black eye with a killing shape, this time the rabbity six (again, a move at a would complete the killing shape).

Failure  

W1 might look like a tesuji at the first glance, but after B2 Black is alive.

Failure - Follow up 1  

This looks similar to the success diagrams, but because of the liberty at a, White can no longer fill Black's eye with a killing shape. The result is seki. If white plays W1 at W3, black still plays B2, with the same result.

Failure - Follow up 2  

If White tries to make a ko with W3, this also fails, as Black has enough liberties to crush the ko with B6.
